The OPTICON MK2 speaker range majors on clear, undistorted, enjoyable and coherent audio - perfectly complementing music, radio, streaming, TV or movie sources. The speaker series caters to every requirement - offering a speaker for every room and every occasion. Comprising six models ranging from a compact on-wall speaker to a towering floorstander.
The new OPTICON MK2 hybrid tweeter marries the CALLISTO-derived 29 mm soft dome with a custom 17 x 45 mm ribbon - mounted on a cast aluminium faceplate that incorporates dispersion control detailing. This combination offers the clarity, speed and dynamics of a dome tweeter, with the very high frequency detail and smooth finesse of a ribbon tweeter.
The newly introduced OPTICON MK2 Dual Flare technique brings port design into the realm of aerodynamics - with exit and entry flares carefully designed to minimise turbulence. Dual Flare enables OPTICON MK2 reflex ports to remain laminar and work effectively to reinforce low frequency performance to a significantly higher volume level than would otherwise be possible.
Speakers used and enjoyed in pairs should also be built as pairs! Our manufacturing process is designed to ensure that stereo pairs of speakers are built and tested sequentially by a single manufacturing technician, using components taken in the same order from the same batch. It’s a process that helps ensure ultimate visual and acoustic pair matching.
The SMC used in OPTICON MK2's magnet motor system has very high magnetic permeability and very low electrical conductivity. It works primarily by minimising eddy currents in the magnet system pole piece. This improves flux linearity, reducing the magnetic hysteresis. Resulting in a significant reduction of electro-acoustic distortion.
An important element of the OPTICON MK2 range is that the production remains fully Danish - as with the original OPTICON series. The entire lineup is manufactured at our own factory from components either produced in-house, or mainly sourced from the best local specialist-manufacturers. We are therefore proud to say that the OPTICON MK2 series is designed, developed and manufactured in Denmark.
The mid-sized OPTICON 2 MK2 speaker is a true 2-way compact performer holding a 6½" wood fibre woofer matched with a new large 29 mm soft dome tweeter derived from the CALLISTO series.
The OPTICON 2 MK2 offers a level of performance unavailable from any other OPTICON model. The stand mount speaker is a natural distributor of high performance audio in compact to medium sized listening spaces where it has room to breathe and deliver its dynamic and explicitly defined performance.
The manufacturing of the OPTICON 2 MK2 remains fully Danish - as with the MK1 series. Fully assembled at our factory in Denmark - from components produced in-house or sourced from the best local specialist manufacturers and further afield.
The OPTICON 2 MK2 is available in Satin Black, Satin White and Tobacco Oak.
As
a reflex loaded speaker, the OPTICON 2 MK2 employs the otherwise unused
acoustic output from the rear of its bass driver to extend low
frequency bandwidth and increase low frequency power handling. We
revisited the port tuning to ensure that the subjective bass performance
was absolutely optimised for its likely installation application.
With
Dual Flare technique, the MK2 brings port design into the realm of
aerodynamics with exit and entry flares carefully designed to minimise
turbulence at the airflow rate expected from the port diameter and
tuning frequency.
Dual Flare enables the reflex ports to remain
laminar and work effectively to reinforce low frequency performance to a
significantly higher volume level than would otherwise be the case.
The
OPTICON 2 MK2 driver magnet system consists of a large ferrite ring
magnet surrounding a pole piece manufactured entirely of the unique DALI
SMC material. The pole piece and the ferrite magnet are secured between
soft iron front and back plates to create the appropriate magnetic
field for the voice-coil.
DALI SMC (Soft Magnetic Compound) is a
coated magnet granular material that can be formed to almost any
desired shape and has many advantages used in driver magnet systems.
SMC’s unusual combination of very high magnetic permeability and very
low electrical conductivity is exactly what is required for driver
magnet systems and results in a significant reduction of
electro-acoustic distortion.
SMC works primarily by minimising
eddy currents in the magnet system pole piece, which reduces distortion.
SMC also improves flux linearity within the magnet system - reducing
magnetic hysteresis. All of these SMC benefits together produce a
significant subjective reduction of low-level detail masking and
colouration.
The new unique light-weight
29 mm soft dome tweeter is derived from CALLISTO C and offers
significant advances over the tweeters used in the MK1 series. The
relatively small increase in diameter over the previous 28 mm tweeter
results in a significant increase in dome radiating area. This means
lower distortion, higher power handling, and an ability to operate at
lower frequencies.
The use of the same 29 mm soft dome tweeter
across all six OPTICON MK2 models results in consistency of tonal
character and provides consistency of dispersion characteristics. The
MK2 soft dome tweeter enables crossover frequencies as low as 2kHz to be
safely employed with no risk of distortion or power handling
limitations.
Every component of the 6½" MK2 driver
is carefully designed for its positive contribution towards ideal
performance. The diaphragms are made from a mix of paper and wood fibre
that ensures minimal break-up resonance and gives the diaphragms their
distinctive DALI trademark colour. They are terminated by rubber
surrounds chosen for their soft and very flexible mechanical properties
that enable free movement with minimal low frequency damping.
The
driver chassis for each driver is manufactured in die-cast aluminium
that provides extremely high rigidity and low resonance along with
minimal extraneous influence on the internal magnet system. The
mechanical design of the chassis is specifically engineered to provide
minimal impedance to airflow while at the same time enabling extremely
tight mechanical bonding with the speaker enclosures.
The driver
were designed with a consistent focus on the DALI audio principles of
low-loss, low distortion and low colouration. The ideal driver plays
only what the amplifier requires, with nothing added and nothing
subtracted, and at DALI we strive to design and manufacture drivers that
approach the ideal as closely as possible.
The
enclosure of the OPTICON 2 MK2 is designed to optimise rigidity and
minimise panel resonance. The 25mm thick front baffle provides massively
rigid foundations for the drivers. The floorstanding speaker employs
extra internal bracing further to ensure rigidity and practically
eliminate panel resonance.
The manufacturing of the OPTICON MK2
series has been retained firmly at the DALI factory in Denmark. Our
in-house woodworking facility handles everything from cutting and
routing the MDF panels to the driver and crossover installation. The
final test and quality approval on each and every speaker is also
handled on our own assembly lines.
